Comment (by acjones8):

 Wait, nevermind, I see the problem now. GCC 12's header disables the
 redefinition if it's running in a C++ environment, since vector is often
 short for std::vector. GCC 7's header never checked if it was running in
 C++ mode, it just unconditionally redefined vector to `__vector` on non-
 Apple systems, and seems to have expected the programmer to undefine it if
 need be.

 {{{
 #if !defined(__APPLE_ALTIVEC__)
 /* You are allowed to undef these for C++ compatibility.  */
 #define vector __vector
 #define pixel __pixel
 #define bool __bool
 #endif
 }}}

 So then, maybe an upstream patch is more appropriate? Maybe I can ask them
 to stick the vector to `__vector` definition in there, since it seems like
 this is what it's doing most of the time anyway.
